A specialized TPad including a TSliderBox object.
The TSliderBox can be moved in the pad.
Slider drawing options include the possibility to change the slider starting and ending positions or only one of them.
The current slider position can be retrieved via the functions TSlider::GetMinimum and TSlider::GetMaximum These two functions return numbers in the range [0,1].
If a method has been set (via TSlider::SetMethod), the expression is executed via the interpreter when the button 1 is released.
if no method has been set, and an object is referenced (TSlider::SetObject has been called), while the slider is being moved/resized, the object ExecuteEvent function is called.
The canvas and the sliders created in the above macro are shown in the picture below.
Same example as above. Instead of TSlider::SetMethod:
When the slider will be changed, MyClass::ExecuteEvent will be called with px=0 and py = 0

Call this function within a function that you don't want to define as purely virtual, in order not to force all users deriving from that class to implement that maybe (on their side) unused function; but at the same time, emit a run-time warning if they try to call it, telling that it is not implemented in the derived class: action must thus be taken on the user side to override it.
In other word, this method acts as a "runtime purely virtual" warning instead of a "compiler purely virtual" error.

Add a new TExec object to the list of Execs.
When an event occurs in the pad (mouse click, etc) the list of C++ commands in the list of Execs are executed via TPad::AutoExec.
When a pad event occurs (mouse move, click, etc) all the commands contained in the fExecs list are executed in the order found in the list.
This facility is activated by default. It can be deactivated by using the canvas "Option" menu.
The following examples of TExec commands are provided in the tutorials: macros exec1.C and exec2.C.
At this point you can use the mouse to click on the contour of the histogram hpx. When the mouse is clicked, the bin number and its contents are printed.
When moving the mouse in the canvas, a second canvas shows the projection along X of the bin corresponding to the Y position of the mouse. The resulting histogram is fitted with a gaussian. A "dynamic" line shows the current bin position in Y. This more elaborated example can be used as a starting point to develop more powerful interactive applications exploiting the C++ interpreter as a development engine.

Build a legend from the graphical objects in the pad.
A simple method to build automatically a TLegend from the primitives in a TPad.
Only those deriving from TAttLine, TAttMarker and TAttFill are added, excluding TPave and TFrame derived classes.
| [in] | x1,y1,x2,y2 | The TLegend coordinates |
| [in] | title | The legend title. By default it is " " |
| [in] | option | The TLegend option |
The caller program owns the returned TLegend.
If the pad contains some TMultiGraph or THStack the individual graphs or histograms in them are added to the TLegend.
If x1 is equal to x2 and y1 is equal to y2 the legend will be automatically placed to avoid overlapping with the existing primitives already displayed. x1 is considered as the width of the legend and y1 the height. By default the legend is automatically placed with width = x1= x2 = 0.3 and height = y1= y2 = 0.21.

Set Current pad.
When a canvas/pad is divided via TPad::Divide, one can directly set the current path to one of the subdivisions. See TPad::Divide for the convention to number sub-pads.
Returns the new current pad, or 0 in case of failure.
For example:
To set the current pad to the bottom right pad, do
Note1: c1.cd() is equivalent to c1.cd(0) and sets the current pad to c1 itself.
Note2: after a statement like c1.cd(6), the global variable gPad points to the current pad. One can use gPad to set attributes of the current pad.
Note3: One can get a pointer to one of the sub-pads of pad with: TPad subpad = (TPad)pad->GetPad(subpadnumber);

Sutherland and Hodgman's polygon-clipping algorithm uses a divide-and-conquer strategy: It solves a series of simple and identical problems that, when combined, solve the overall problem. The simple problem is to clip a polygon against a single infinite clip edge. Four clip edges, each defining one boundary of the clip rectangle, successively clip a polygon against a clip rectangle.
Steps of Sutherland-Hodgman's polygon-clipping algorithm:
The clip boundary determines a visible and invisible region. The edges from vertex i to vertex i+1 can be one of four types:

Disconnects signal in object sender from slot_method in object receiver.
For objects derived from TQObject signal-slot connection is removed when either of the objects involved are destroyed.
Disconnect() is typically used in three ways, as the following examples shows:
0 may be used as a wildcard in three of the four arguments, meaning "any signal", "any receiving object" or "any slot in the receiving object", respectively.
The sender has no default and may never be 0 (you cannot disconnect signals from more than one object).
If signal is 0, it disconnects receiver and slot_method from any signal. If not, only the specified signal is disconnected.
If receiver is 0, it disconnects anything connected to signal. If not, slots in objects other than receiver are not disconnected
If slot_method is 0, it disconnects anything that is connected to receiver. If not, only slots named slot_method will be disconnected, and all other slots are left alone. The slot_method must be 0 if receiver is left out, so you cannot disconnect a specifically-named slot on all objects.

Automatic pad generation by division.
Pads are automatically named canvasname_n where n is the division number starting from top left pad.
Example if canvasname=c1 , nx=2, ny=3:
Once a pad is divided into sub-pads, one can set the current pad to a subpad with a given division number as illustrated above with TPad::cd(subpad_number).
For example, to set the current pad to c1_4, one can do:
Note1: c1.cd() is equivalent to c1.cd(0) and sets the current pad to c1 itself.
Note2: after a statement like c1.cd(6), the global variable gPad points to the current pad. One can use gPad to set attributes of the current pad.
Note3: in case xmargin < 0 or ymargin < 0, there is no space between pads. The current pad margins are recomputed to optimize the layout in order to have similar frames' areas. See the following example:

This has no negative side-effect as searching for the object with the right or wrong Hash will always yield a not-found answer (Since anyway no hash can be guaranteed unique, there is always a check)

Save Canvas contents in a file in one of various formats.
root: a ROOT binary file
filename = 0 - filename is defined by GetName and its extension is defined with the option
When Postscript output is selected (ps, eps), the canvas is saved to filename.ps or filename.eps. The aspect ratio of the canvas is preserved on the Postscript file. When the "ps" option is selected, the Postscript page will be landscape format if the canvas is in landscape format, otherwise portrait format is selected.
The physical size of the Postscript page is the one selected in the current style. This size can be modified via TStyle::SetPaperSize.
Examples:
where TStyle::kA4 and TStyle::kUSLetter are defined in the enum EPaperSize in TStyle.h
An alternative is to call:
The above numbers take into account some margins and are in centimeters.
The "Preview" option allows to generate a preview (in the TIFF format) within the Encapsulated Postscript file. This preview can be used by programs like MSWord to visualize the picture on screen. The "Preview" option relies on the "epstool" command.
Example:
The "EmbedFonts" option allows to embed the fonts used in a PDF file inside that file. This option relies on the "gs" command.
Example:
The "Standalone" option allows to generate a TeX file ready to be processed by tools like pdflatex.
Example:
Example:
In the previous example replacing "ps" by "pdf" will create a multi-pages PDF file.
Note that the following sequence writes the canvas to "c1.ps" and closes the ps file.:
The TCanvas::Print("file.ps(") mechanism is very useful, but it can be a little inconvenient to have the action of opening/closing a file being atomic with printing a page. Particularly if pages are being generated in some loop one needs to detect the special cases of first and last page and then munge the argument to Print() accordingly.
The "[" and "]" can be used instead of "(" and ")" to open / close without actual printing.
Example:
As before, the same macro is valid for PDF files.
It is possible to print a canvas into an animated GIF file by specifying the file name as "myfile.gif+" or "myfile.gif+NN", where NN*10ms is delay between the subimages' display. If NN is omitted the delay between subimages is zero. Each picture is added in the animation thanks to a loop similar to the following one:
The delay between each frame must be specified in each Print() statement. If the file "myfile.gif" already exists, the new frame are appended at the end of the file. To avoid this, delete it first with gSystem->Unlink(myfile.gif); If you want the gif file to repeat or loop forever, check TASImage::WriteImage documentation

Redrawing axis may be necessary in case of superimposed histograms when one or more histograms have a fill color.
Instead of calling this function, it may be more convenient to call directly h1->Draw("sameaxis") where h1 is the pointer to the first histogram drawn in the pad.
By default, if the pad has the options gridx or/and gridy activated, the grid is not drawn by this function.

Asynchronous pad update.
In case of web-based canvas triggers update of the canvas on the client side, but does not wait that real update is completed. Avoids blocking of caller thread. Have to be used if called from other web-based widget to avoid logical dead-locks. In case of normal canvas just canvas->Update() is performed.

Loop and sleep until a primitive with name=pname is found in the pad.
If emode is given, the editor is automatically set to emode, ie it is not required to have the editor control bar.
The possible values for emode are:
If emode is specified and it is not valid, "PolyLine" is assumed. If emode is not specified or ="", an attempt is to use pname[1...]
for example if pname="TArc", emode="Arc" will be assumed. When this function is called within a macro, the macro execution is suspended until a primitive corresponding to the arguments is found in the pad.
If CRTL/C is typed in the pad, the function returns 0.
While this function is executing, one can use the mouse, interact with the graphics pads, use the Inspector, Browser, TreeViewer, etc.
Examples:
The following macro waits for 10 primitives of any type to be created.
If ROOT runs in batch mode a call to this method does nothing.

Write this object to the current directory.
The data structure corresponding to this object is serialized. The corresponding buffer is written to the current directory with an associated key with name "name".
Writing an object to a file involves the following steps:
Bufsize can be given to force a given buffer size to write this object. By default, the buffersize will be taken from the average buffer size of all objects written to the current file so far.
If a name is specified, it will be the name of the key. If name is not given, the name of the key will be the name as returned by GetName().
The option can be a combination of: kSingleKey, kOverwrite or kWriteDelete Using the kOverwrite option a previous key with the same name is overwritten. The previous key is deleted before writing the new object. Using the kWriteDelete option a previous key with the same name is deleted only after the new object has been written. This option is safer than kOverwrite but it is slower. NOTE: Neither kOverwrite nor kWriteDelete reduces the size of a TFile– the space is simply freed up to be overwritten; in the case of a TTree, it is more complicated. If one opens a TTree, appends some entries, then writes it out, the behaviour is effectively the same. If, however, one creates a new TTree and writes it out in this way, only the metadata is replaced, effectively making the old data invisible without deleting it. TTree::Delete() can be used to mark all disk space occupied by a TTree as free before overwriting its metadata this way. The kSingleKey option is only used by TCollection::Write() to write a container with a single key instead of each object in the container with its own key.
An object is read from the file into memory via TKey::Read() or via TObject::Read().
The function returns the total number of bytes written to the file. It returns 0 if the object cannot be written.
